Pair this classic green bean casserole with other holiday favorites like a sweet potato casserole.

📜 A Dish Rooted in American History

This beloved side dish was originally created in 1955 by Dorcas Reilly, a home economist working in the Campbell’s Soup test kitchen. Her goal was to create a recipe that used ingredients already found in most American kitchens.

As noted by Smithsonian Magazine, Reilly’s recipe was part of a broader effort to simplify cooking and appeal to the growing number of working households.

🧂 Why Is It So Popular?

The appeal lies in its simplicity and comforting flavor. The combination of green beans, cream of mushroom soup, and crispy fried onions creates a nostalgic experience for many. Plus, it’s easy to adapt with fresh ingredients or gourmet upgrades.

When preparing casseroles—especially ones you plan to freeze or refrigerate—refer to the FDA’s food safety storage guidelines to ensure quality and safety, especially during the busy holiday season.

🛒 Essential Ingredients for Classic Green Bean Casserole

When it comes to preparing a Classic Green Bean Casserole, the magic lies in its simplicity. With just a handful of pantry staples, you can create a comforting, flavorful side dish that complements any holiday spread. Let’s break down the essential ingredients that define this iconic dish, along with tips and variations to make it your own.

✅ Core Ingredients

Here are the time-tested basics that every green bean casserole recipe starts with:

1. Green Beans

The foundation of the dish. You have three main options:

• Fresh Green Beans – Best for texture and flavor. Trim and blanch them before use to maintain that bright green color and slight crunch.
• Frozen Green Beans – Convenient and close in quality to fresh. No trimming needed, just thaw and drain well.
• Canned Green Beans – The traditional option for many households. Soft in texture and pre-cooked. Drain thoroughly to avoid sogginess.

💡 Tip: Use French-style cut green beans if you want a more delicate, tender bite.

2. Cream of Mushroom Soup

This is what gives the casserole its creamy, savory base. The original 1955 recipe by Campbell’s made this a staple in American homes. You can:

• Use a store-bought can (typically 10.5 oz)
• Make your own mushroom béchamel sauce for a fresher, healthier alternative
• Substitute with cream of celery or cream of chicken for a flavor twist

3. Milk

Thins out the soup to create the perfect consistency. Whole milk is most commonly used, but you can substitute with:

• Low-fat milk for fewer calories
• Half and half for richer flavor
• Unsweetened almond or oat milk for dairy-free versions

Use about ½ cup of milk per can of soup.

4. Soy Sauce

This may surprise some, but it’s a key player. Just a splash (around 1 teaspoon) adds umami depth that enhances the earthy mushroom flavor. You can also use:

• Tamari (gluten-free)
• Worcestershire sauce for added complexity

5. Black Pepper

Simple, but essential. Freshly ground black pepper balances the creamy and salty components. Start with ¼ teaspoon and adjust to taste.

🍽️ Topping: Crispy Fried Onions

No classic green bean casserole is complete without its signature crunchy topping.

• French’s Crispy Fried Onions are the traditional go-to.
• You can make your own by:
  • Thinly slicing shallots or onions
  • Coating them in flour
  • Frying or air-frying until golden

Add half to the casserole before baking for extra onion flavor, and reserve the rest for that golden-brown final layer. Add color and variety to your holiday table with these festive baked sweet potatoes.

🛍️ Optional Add-Ins

While not in the original recipe, many cooks love to customize with:

• Shredded cheddar cheese
• Crumbled bacon
• Sauteed garlic or shallots
• Mushroom pieces for texture
• Cayenne pepper or smoked paprika for a mild kick

🧑‍🍳 Summary

By combining just a few humble ingredients, the classic green bean casserole transforms into a flavorful, creamy, and crispy dish that defines holiday comfort food. Whether you stick with tradition or add your personal twist, these ingredients are the backbone of a dish that never goes out of style.
